Lemon DSM2 6-Channel Receiver (PPM + UART) Spektrum Compatiable
$12.00
Description
This product can be use as a standalone receiver. PPM / UART output gives the flexibility for more complicated application including UAV (Unmanned Air Vehicle) / robotics platform.

| Dimension: | 37(L) x 18(W) x 11(H) mm |
| Weight: | 3.7 gram |
| Voltage Range: | 3.45 – 10.2 V |
| PPM / UART output: | TTL compatible |
TX port (UART, 9600bps, 8N1)
Condition 1) UART output specification when no signal received (device reset and continuously monitor for valid signal every 0.5 sec):
– <0x13><‘R’><‘E’><‘S’><‘E’><‘T’><0x13>
– <0x13> is used as header for beginning and ending identifier
Condition 2) UART output specification when signal is received ( updated ~40ms with 8 bytes of information):
– <0x13><Aileron><AUX><Gear> Elevator><Throttle><Rudder><0x13>
– DEC(66) ~ DEC(134) refer to the approximate value for each of the full range control output for the 6 channels.
– <0x13> is used as header for beginning and ending identifier
For example: if all channels are centered except throttle shutdown and AUX is maximized, the UART should output the following.
<0x13><DEC(100)> <DEC(134)> <DEC(100)> <DEC(100)> <DEC(66)> <DEC(100)><0x13>
PPM port
Condition 1) PPM pulled to ground (logic level low).
Condition 2) If signal is valid, 6 high pulses are used to represent Aileron, AUX, Gear, Elevator, Throttle and Rudder while each signal is separated by ~60us low pulse. ~40ms low pulse followed and continues the updates from receiver.

Vreg port
On board Vreg output is available as reference voltage for logical high signal. Do not exceed drawing over 10mA of current.
NA port
Do not connect anything to this pin. NA pin is a direct connection to reset the microprocessor. The microprocessor has already pre-programmed a watchdog timer which will ensure the reliability of the unit’s long term operation by auto reset in case of any system failure / temporary power failure and resume operation in 0.5 sec.
GND port
System ground.
